Thrilled to learn our (@theori_io) CRS got first place in the AIxCC Semifinal competition. For the semifinal competition, we focused on implementing simple ideas in a robust way. I'm eager to implement our more ambitious ideas for the final event next year!

🚨 New Linux Kernel vulnerability (CVE-2024-27394) discovered & patched by Theori!
🔗 blog.theori.io/deep-dive-int…
Our researcher @v4bel at #Theori identified a critical #UAF vulnerability in TCP-AO caused by a race condition in the #RCU API. Using techniques from the ExpRace paper, we extended the race window to demonstrate its exploitability.
Curious how we did it?
Read our deep dive for the full details!

In a recent #APT simulation, #Theori uncovered 4 critical #RCE vulnerabilities in @cososys Endpoint Protector (EPP) that let us fully compromise the server & clients. Here’s a peek:
👾 CVE-2024–36072: Unauthenticated attackers can exploit a logging flaw to execute system commands with root privileges.
👾 CVE-2024–36073: With admin access, attackers can overwrite configurations and execute commands on client endpoints.
👾 CVE-2024–36074: Server access allows attackers to execute malicious files.
👾 CVE-2024–36075: Unauthenticated attackers can manipulate client configurations to potentially bypass security and achieve remote code execution.
Could your server be #hacked the same way? Find out through our blog post!

We just pwned VMware and Windows11
Confirmed! Gwangun Jung (@pr0ln) and Junoh Lee (@bbbig12) from Theori (@theori_io) combined three different bugs to escape #VMware Workstation and then execute code as SYSTEM on the host OS. This impressive feat earns them $130,000 and 13 Master of Pwn points. #Pwn2Own

Wow! The Theori was able to exploit VMware Workstation with an additional Windows Kernel LPE vulnerability in the Virtualization category. They went from guest OS to SYSTEM on the host OS. They're off to the disclosure calls with details. #Pwn2Own

Do you use a virtual machine to browse dangerous links safely? If you use the Chrome browser inside that virtual machine, is it secure enough?
As you might have guessed, the answer is not so much.
We chained six unique CVEs from 2023 listed below.
• Chrome Renderer RCE : CVE-2023-3079
• Chrome Sandbox Escape : CVE-2023-21674
